Calibration of a Camera and Light Source by Fitting to a Physical Model

December 31, 1986
Author(s)
P Mansbach
This paper describes the calibration of a camera-and-plane-of-light ranging system. Equations are derived which relate the image coordinates in the camera to the external coordinate system. These equations contain coefficients which are functions of the

Merging 3-D Symbolic Descriptions Obtained from Multiple Views of a Scene

October 31, 1986
Author(s)
Martin Herman
An algorithm is presented for merging three-dimensional symbolic descriptions of static polyhedral scenes obtained from multiple viewpoints. The 3-D descriptions are assumed to be partial because of occulusions. The merging algorithms treats the topology

Non-Linear Contour-to-Grid Digital Interpolation

October 10, 1986
Author(s)
Betty Mandel, Christoph J. Witzgall, Javier Bernal
A technical approach to the task of performing a contour to grid conversion using nonlinear interpolation has been studied. The approach consists of reconstructing a terrain surface from the digitized contour lines on a map. The approximating surface is
